The Satan 2, officially known as the RS-28 Sarmat, has been an open secret for a while now as Russia has more or less engaged in the geopolitical equivalent of a marketing campaign. And this is no different, as the first specs were declassified by the Makeyev Rocket Design Bureau. On paper, the missile is state of the art, able to evade radar defenses and travel far enough to hit the East or West Coast of the US with a payload that could destroy an area the size of Texas.

Similarly, Russia is notably talking about the Satan 2 right when the original Satan missiles that carry Russia's warheads are reaching the end of their operational life. So like anything with years of hype behind it, take that hype with a grain of salt. Russia will almost certainly remain a nuclear power, and that's worrying in light of their recent behavior, but the claims of parity, or superiority, to the US nuclear arsenal will hopefully never have to be proven.
